room(0.0.0):
    description: $(equals:light,0;You are standing. But it's hard to say where,
                 because it's dark. You can't see anything. Just black
                 everywhere.

                 It seems there's some large object on the floor. You can feel
                 it using your legs, but it's too dark to see what it is.)$

                 $(equals:light,1;You are in a small room, lit by a
                 power-saving, environment-friendly light bulb attached to the
                 ceiling.

                 There is a stationary bicycle standing here.

                 There is an exit to the north, leading to another room.)$
    items: object, bicycle, bulb
    exits: north.1

exit(1):
    fail: Where? I can't see!
    equals: light,1

item(object):
    on_examine: $(equals:light,0;It's dark, you can't see it. But you could try
                to touch it.)$
                $(equals:light,1:It's a stationary bicycle.)$
    on_touch: Hmmm... it seems to be a stationary bicycle. Like the ones you
              can find in a gym.

item(bicycle):
    on_examine: It's a stationary bicycle. People use them for exercise and
                for generating electricity.
    on_ride: You sit on the bicycle and start riding. It's very difficult to
             move, maybe due to rust. But it seems to generate power! And that
             power is now powering a light bulb. Woohoo, I can see!#(light=1)#

item(bulb):
    on_examine: It's a power-saving, environment-friendly light bulb. When it
                stops working, which will happen in roughly a hundred years, it
                can be recycled into a new light bulb.
